摘要: <正> 电测量指示仪表标度盘的刻度、数字、符号等合理配置的研究,是工程心理学的一个重要组成部分。开关板电表,由于观察距离随工作现场的情况而有相当大的差别,刻度线的粗细、长短、间隔对阅读速度及准确度的影响,便显得更为重要了。本文就是有关课题的一系列研究报告之一。

Abstract: The effects of dial scale mark length, thickness, spacing and observing distance onreading speed and accuracy were studied under laboratory conditions. Preliminary ex-periments with simplified scales revealed that length and thickness are not as important asseparation of scale marks. These findings were verified by using simulated instrumentials as testing objects. Further experiments indicated that there exist lower limits forlength and thickness of scale mark, that the equal visual angle made by scale markdimensions and separation gives equal legibility, no matter what the observing distanceis, and that the legibility is a function of the visual angle made by the separation betweencale marks. Under our experiment conditions, this relation can be expressed by thequations, RT=1.41/α+91.2 and E=0.17/α~(1.71), where RT denotes reading reaction time,E, per cent reading errors, and α, visual angle of separation between scale marks inegree.
